Troubleshooting Bigcommerce


Processing Standard Invoice Discounts

There is currently a known limitation with the Bigcommerce system where standard discounts get automatically applied on the very first item on the invoice.

This issue occurs when a standard discount is applied to the invoice:


Standard discounts will show up on your BC interface as follows:

However, the Bigcommerce API will send the discounts over as if the first item on the invoice is discounted.

Usually this would be ok, however when the data goes into the accounting system it will affect profit/loss reporting within the accounting system.

We are currently in the process of working this out with Bigcommerce directly to see how we can get this working properly.


When integrating Bigcommerce, you may find you get the following (429) error in your initial sync report:

"OneSaas.Framework.ProcessingException: Could not communicate with ''.
The remote server returned an error: (429) Client Error (429)."

This error can occur when you have too many apps connected to your Bigcommerce store, therefore we are hitting Bigcommerce's limits. To get past this, please do the following:

  1. leave your file for 24 hours
  2. try another sync 

Now, the Bigcommerce limits should have re-set, and the error should no longer be there. If the error persists, please contact our support team for further investigation.



Unable to connect up Bigcommerce, the app just logs into the Bigcommerce admin screen and does nothing:

Please make sure you are using the Owner login to set up the integration. The Bigcommerce system will not allow the connection to be set up without the Owner login.
